Energy medicine is a branch of alternative medicine based on a pseudo-scientific belief that healers can channel "healing energy" into a patient and effect positive results. In most cases there is no empirically measurable energy involved: the term refers instead to so-called subtle energy. Practitioners may classify practice as hands-on, hands-off, and distant where the patient and healer are in different locations. Many schools of energy healing exist using many names: for example, bio-field energy healing spiritual healing, contact healing, distant healing, therapeutic touch, Reiki or...

Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing carbon dioxide (CO2) before it enters the atmosphere, transporting it, and storing it (carbon sequestration) for centuries or millennia. Usually the CO2 is captured from large point sources, such as a chemical plant or biomass power plant, and then stored in an underground geological formation. The aim is to prevent the release of CO2 from heavy industry with the intent of mitigating the effects of climate change. Although CO2 has been injected into geolo- gical formations for several decades for...

Meeting existing and future energy demands in a sustainable way is a critical challenge for the global goal of limiting climate change while maintaining economic growth and enabling living standards to rise. Reliable and affordable energy, particularly electricity, is essential for health care, education, and economic development.Improving energy access in the least-developed countries and making energy cleaner are key to achieving most of the United Nations 2030 Sustainable Development Goals, which cover issues ranging from climate action to gender equality. Sustainable Development Goal 7...

Verschiedene Materialien und Wandlermechanismen sind in der Lage, Schwingungsenergiein nutzbare elektrische Energieumzuwandeln, z. B. piezoelektrische, elektromagnetische und elektrostatische Generatoren. Piezoelektrische Wandler mit ihrer inhärenten elektromechanischen Kopplung und ihrer hohen Leistungsdichte im Vergleich zu elektromagnetischen und elektrostatischen Wandlern sind weithin erforscht worden, um Strom aus Schwingungsenergiequellen zu erzeugen.Viele Forscher haben in den letzten zehn Jahren über neuartige Anwendungen der piezoelektrischen Energy Harvesting-Technologie...

Divers matériaux et mécanismes de transduction ont la capacité de convertir l'énergie vibratoireen énergie électrique utile, comme les générateurs piézoélectriques, électromagnétiques et électrostatiques. Les transducteurs piézoélectriques, avec leur couplage électromécanique inhérent et leur densité de puissance élevée par rapport aux transducteurs électromagnétiques et électrostatiques, ont été largement explorés pour générer de l'énergie à partir de sources d'énergie vibratoire.Au cours de la dernière décennie, de nombreux chercheurs ont fait état de...
